Place additional textures to /sdcard/.cr3/textures/ -- to be used as tiled page backgrounds.Place additional textures to /sdcard/.cr3/backgrounds/ -- to be used as stretched page backgrounds.(/cr3/ directory can also be used instead of /.cr3/, and internal SD or internal storage instead of /sdcard/)

CoolReader requires following permissions:WAKE_LOCK - to control screen backlightWRITE_EXTERNAL_STORAGE - to access SD cardINTERNET - to use online catalogs

In case of issues after update (e.g. crashes while reading) try to remove directory SD/.cr3/cache and book database files SD/.cr3/*.sqlite

Windows version can be downloaded here:http://sourceforge.net/projects/crengine/files/CoolReader3/cr3-newui-opengl/cr3-win32-qt-opengl-3.3.48.zip/download

As well, consider using "Cool Reader GL" - cross-platform Cool Reader version with UI rewritten in C++, with hardware acceleration based on OpenGL. Optimized for new devices with big high resolution screens. Both versions can be installed together.

The best ereader! I really love it. It is nice that you can customise just about everything you like! The only thing is, I wish you could synchronise your progress/bookmarks across all your devices. So I can read on my phone when I'm on the go and carry on on my tablet at home without manually entering the new spot. Would it be possible to do that at all? Perhaps with a log in. But otherwise this app is perfect! Always works well and a joy to use!

Needs cross-device synchronisation This is my favourite eBook reader. It does almost everything I need. The only thing it lacks is cross-device synchronisation to allow me to read from where I left off no matter which device (phone or pad) I pick up. Maybe having the app save its book position/mark index to Google drive (or any similar cloud provider) would do the trick. I'm awarding all five stars anyway, but would love to see a synch feature in a future update.

Problem in Android Lollipop It used to be my favorite epub reader app. Back when I was still using Android Jelly Bean, it worked perfectly. But it doesn't seem to work in my new phone (with Android Lollipop). When I try to reduce the screen backlight brightness to the lowest level, the text becomes blurr. It was perfectly fine in my Android Jelly Bean though. So I wonder why it won't work in Lollipop? Can I just send this problem through email so i can show you the screenshoot? Please respond me 😭

Still many glitches Love this app especially the read aloud option can still read my ebooks while I'm multitasking. Always re-install when I change phones but the glitches seem to be getting worse. Forces close all the time even in read aloud mode and constantly loses the page that I was on when I close it.

THE ABSOLUTE BEST READING APP This app really rocks! It won't disappoint You, cool reader reads books when all other readers fail! UB reader failed to read something but this read it! It looks a bit bad but it works better than anything. I even somehow managed to download the messages off a social network and read THEM as a book! Beyond compare, you will love it, do rate it 5 stars!

Old but very good Highly customizable, every option you could want including advanced font settings, custom touch areas, titlebar with progress meter and/or battery % and clock. Bug with TTS where skipping backward results in voice skipping backward but highlight skipping forward.

Loved this app used it for years but got new phone LG g4 downloaded cool reader but it can't find my ext SD card now so can't read my books gutted this was best AP out there Help fix this problem please

Cut off sentences, but looked good. Unfortunately sentences, even those climactic ones at the end of chapters, were cut off from the second or third word; using another app showed the whole sentence, meaning that this app is faulty in some way. It's a pity, because I liked the look and feel of this app along with the slide screen brightness.

Really like it but there is a rotation bug Works great and been using it for a while. The biggest problem I have had is the screen auto rotates in the app no matter what the global setting is. It's frustrating if you want to lay on your side and read as the screen turns 90 degrees. This is about the only app I have come across that ignores the global setting.

Can't see external SD card Love this app, but just got a new phone with Marshmallow and it can't see the SD card. I see reviews reporting this 6 months ago, so not hopeful this will be fixed. I guess it's the end of the road for me. :(

Excellent reader with many options I have been using this reader for many years, and it has always served me well. As another reviewer has mentioned however, it seems that in Android 6.0, files located on an external SD card cannot be opened by cool reader. I hope this is fixed in an update soon.

Amazing! Allowed me to read many books in situations in which I couldn't have. Really practical and easy to use. Cool fact : you can quickly search words you don't understand in the dictionary, so it's perfect for reading in foreign languages!

Very good reader, but force closes constantly Very good app, used to be my go-to ebook reader, but recently began to constantly force-close and lose track of the page of the book i'm currently reading. hope this would be fixed soon. meantime, i'm using a competing reader... Edit: using Samsung Galaxy Tab S 8.4 and 5.0.2.

Would give it 5 stars, but... It crashes at random on my Galaxy s7 and my Galaxy Tab s2. Other than that of love the app. I've been using it for years now, and it may crash but it hasn't failed me yet.

Great ebook reader Can't say it's the best, just because after using it for several years on several devices I never wanted to try another app to compare, because this one has everything I need. It's good enough.

Works well but looks disgusting Great app but it looks vile. Everything from the icon to the app background is revolting. I won't have it on my desktop as the icon is so dreadful. If the dev sorts out the aesthetics I'd give it 5 stars.

Until kitkat that was awesome app. Since marshmallow it's nearly useless The problem is with permissions, obviously. It won't even try to access my external SD card. Sad, because this is perfectly doable (some other ebook readers can do it)

Wish I could use an old version Used to be awesome but now the text to speech skips words, sentences, and sometimes even whole paragraphs. Has been getting progressively worse for at least a year on multiple devices.

Android 6, Does not see my ext SD card Since the upgrade to Android 6, it does not seem to be able to access my external SD card to read my ebooks. Have used it for years. Cannot use it now. Please fix!

I recently purchased Samshung Galaxy Tab S2 and the same got uprgaded to Android 6.0.1 i.e. Marshmallow. After that, this software is not able to read epub and any other files from MicroSD card. These are showing as txt files . So this software has now become useless for me. May be sone future update will fix this, But fo rnow, this is a major problem with this software.

I love the application! I only would have one wish to make it SUPER perfect. cloud saving for the book. So I can read the book on all my devices and dont need to remember where I left on my phone, when opening it on the tablet. This would be worth a HUGE donation :-)

External sd card is NOT a location option I get internal or emulated sd internal, but can't file path to actual external sd card. I have current phone and Android os, and moving files another time is not worth it. Looking for a fix out working app, which ever comes first. Having a reader versatile with formats read and other customization is great. This was my default reader. The initial page load is slower than kindle and bookmarks work, but could be refined and a little more visual.
